note 89691 deleted from function.str-split by crell

Note Submitter: mattias at lsahlin dot se ---- For those it may concern: We encountered trubble when trying to str_split a UTF-8 encoded string, containing such Swedish letters as å, å and ö. It seems that this function splits according to byte-length and not character length. So if the letter "Å" takes 2 bytes, then str_split() will only return the first bite of the character "Å". We ain't 100% sure that this is the case but this was anyhow the result we got. So we used the multi-byte functions instead.
